Holiday Side Dish Recipes

I’ve shared a lot of holiday recipes here, but there is ALWAYS room for a new holiday side dish on the table. As much as I like to make the same top Thanksgiving dishes every year, it’s nice to add in different recipes to change things up. And I’m always looking for different sides to serve for Christmas dinner.

This Creamed Spinach Casserole was MADE for the holidays. At the base is spinach, a healthy, leafy green that we should all probably eat more of. But it’s mixed with cream and cheese, topped with bread crumbs, and baked into a hot and bubbly casserole. Did I mention it’s cheesy? That combination just calls out to me on the holidays, when I want my vegetables, but covered in something super tasty.
